Filters For 30mm And 40mm Fans

Upgrade you printer with these simple air filters! They filter out dust particles which would otherwise make your printer look messy and reduce your fans' cooling capabilities. To build these you need small pieces of nylon fabric, which you can easily get from (fresh & clean^^) nylon socks.

You will be surprised by how much dust these filters collect within a few days!

Instructions

This design consists of two parts - a simple ring and a mount.

Cut out a slightly bigger piece of fabric than needed and wrap it around the printed ring. Apply some glue on the inside of the holder and press in the ring with the nylon fabric. After a short period of time, trim off the excess material and screw them onto your fans.
